Also, the conductor against Akal-Jodhpur-New (U/C) 400kV D/C line had been mentioned as twin moose instead of quad moose. The same needs to be corrected 1.4 CEA stated that “(a) Akal-Jodhpur 400kV D/C line – 230 km Twin Moose line” mentioned at S.no 1 of the table given at item no 2.8 under the heading Remarks / Justification may be read as (a) “Akal- Jodhpur (Soorpura) 400kV twin moose line (20.22 km D/c & 204.366 km S/c)” and “(c) Akal-Jodhpur-New (U/C) 400kV D/C line- 240 km Twin Moose” may be read as “(c) Akal-Jodhpur-New (U/C) 400kV D/C line – 240 km Quad Moose”. 1.5 Members confirmed the minutes of 1st meeting of NRSCT with the above corrections suggested by RVPNL. 2.0 Evolution of transmission scheme for integration of envisaged RE generation capacity in Solar & Wind Energy Zones and Transmission Schemes for Solar Energy Zones (SEZs) in Rajasthan. 2.1 CEA stated that the transmission scheme for integration of envisaged RE generation capacity in Solar & Wind Energy Zones and Transmission Schemes for Solar Energy Zones (SEZs) in Rajasthan was deliberated in 1st meeting of NRSCT held on 11.9.2018. The scheme mainly envisaged the following SEZs (10 GW) in Rajasthan based on Stage- II applications already received near Fatehgarh, Bikaner and Bhadla as well as Solar Potential pockets in Western Rajasthan as indicated by SECI for SEZ phase-I development: Part-A: i) Fatehgarh SEZ (4 GW) (Fatehgarh-I : 1.2 GW, Fatehgarh-II : 2.8 GW) ii) Phalodi / Bhadla SEZ ( 3 GW) (Bhadla-I : 0.8 GW, Bhadla-II : 2.2 GW) iii) Bikaner – Pugal SEZ (1.85 GW) MoM of 2nd NRSCT held on 13.11.2018 3 File No.CEA-PS-11-21(19)/3/2018-PSPA-I Division-Part(1) 108 I/3021/2018 Part-B: i) Ramgarh / Kuchcheri SEZ (1.15 GW) 2.2 He further stated that the transmission system evolved through system studies was deliberated in 1st meeting of NRSCT held on 11.9.2018 in Delhi, wherein, it was agreed that a separate meeting of CEA, CTU, RVPNL and HVPNL would be called on 20th September, 2018 to further deliberate and study the proposed scheme. Therefore, a meeting was held on 20.9.2018 in Gurgaon, wherein, RVPNL and HVPNL had suggested some modifications in their intra-state network. Based on their suggestions, revised studies were carried out for various scenarios like off peak, Solar minimised / maximised, peak demand for the proposed transmission scheme. It was decided that the scheme may be prioritised out of phase-I Rajasthan REZ capacity (10 GW) considering LTA / Stage-II connectivity applications and some part of the future potential. Accordingly, transmission system was evolved for evacuation of power from Fatehgarh (4 GW), Phalodi/Bhadla (3 GW), Bikaner (1.85GW) (Part –A) and from Ramgarh / Kuchcheri in Fatehgarh (1.15 GW*) (Part-B). 2.3 Subsequently, as requested by RVPNL, a meeting was held on 9.10.2018 (copy of the minutes enclosed as Annexure–II) under the Chairmanship of Director (Op) & Director (Tech), RVPNL in RVPNL office at Jaipur, wherein, based on various studied scenarios, following transmission system was technically agreed for evacuation of power from the generation projects for which applications for Stage-II/LTA in Phalodi/Bhadla, Fatehgarh & Bikaner complex has been received as well as some part of future potential in above complexes : i) Establishment of 765/400/220kV, 3x1500MVA (765/400kV), 5x500 MVA (400/220kV) pooling station at suitable location near Phalodi/ Bhadla in Jodhpur (Bhadla-II) ii) Establishment of 765/400kV, 2x1500 MVA S/s at suitable location near Khetri iii) Augmentation of transformation capacity at Bhadla (PG) by 400/220kV, 2x500MVA (6th & 7th) transformers iv) Creation of 220 kV level at Bikaner (PG) with transformation capacity of 2x500MVA, 400/220kV transformers v) LILO of both circuits of Ajmer – Bikaner 765kV D/c line at Bhadla-II vi) Bhadla-II – Bhadla (PG) 400kV D/c Line (Twin HTLS) vii) Bikaner(PG) – Khetri S/s 765kV D/c line viii) LILO of both circuits of Phagi – Bhiwani 765kV D/c line at Khetri S/s ix) Khetri – Sikar (PG) 400kV D/c line (Twin HTLS) x) Augmentation with 765/400kV, 1x1500MVA transformer (3rd) at Moga S/s xi) Augmentation with 765/400kV, 1x1000MVA, transformer (3rd) at Bhiwani (PG) S/s xii) Establishment of Transformation capacity at Fatehgarh (TBCB) with 3x500MVA, 400/220kV transformers xiii) Establishment of 400/220kV, 4x1500MVA (765/400kV), 5x500 MVA (400/220kV) pooling station at suitable location near Fatehgarh in Jaisalmer Distt (Fatehgarh-II) xiv) Fatehgarh-II – Bhadla -II 765kV D/c line xv) LILO of both circuits of Fatehgarh (TBCB) – Bhadla (PG) 765 kV D/c line (op. at 400kV) at Fatehgarh-II so as to establish Fatehgarh (TBCB) – Fatehgarh -II 765 kV D/c line (to be op. at 400kV) and Fatehgarh-II-Bhadla (PG) 765kV D/c line MoM of 2nd NRSCT held on 13.11.2018 4 File No.CEA-PS-11-21(19)/3/2018-PSPA-I Division-Part(1) 109 I/3021/2018 xvi) Charging of Fatehgarh-II –Bhadla section at 765kV level xvii) Ajmer (PG)– Jhatikara 765kV D/c line xviii)1x125 MVAr (420kV), 2x240 MVAr (765kV) Bus Reactor each at Fatehgarh-II, Bhadla-II & Khetri Substation xix) 1x330 MVAR Switchable Line reactors for each circuit at each end of Ajmer – Jhatikara 765kV D/c line xx) 1x240 MVAr Switchable line reactor for each circuit at each end of Bikaner – Khetri 765kV D/c line xxi) 1x330 MVAr Switchable line reactor for each circuit at Bhadla-II end for Ajmer- Bhadla-II 765kV line (after LILO) xxii) 1x240 MVAr Switchable line reactor for each circuit at Bhadla-II end for Bikaner- Bhadla-II 765kV line (after LILO) xxiii)220kV line bays for interconnection of solar projects at Fatehgarh-II (9 nos), Bhadla-II (9 nos) and Bikaner (4 nos) S/s It was also decided that scheme for evacuation of power from Ramgarh/Kuchcheri in Jaisalmer & additional potential of Rajasthan SEZ may be taken up subsequently based on stage-II connectivity/LTA applications. In the 2nd NRSCT meeting, RVPNL again requested to see the impact of new proposed transmission system on Rajasthan intra-state transmission system. Accordingly, CTU showed load flow cases carried out for various scenarios to the stakeholders including RVPNL to observe incidental power flow due to these interconnections in RVPNL network, which were found in order. CTU stated that presently 6,430MW stage-II connectivity applications are granted at Bhadla (3380MW at 220kV level), Fatehgarh (2200MW at 400kV level) and Bikaner (850MW at 400kV level). Out of above, new stage-II connectivity application is for about 3100 MW in above complexes. Further, LTA of about 3330 MW is already granted with under construction Bhadla / Fatehgarh Solar park transmission system along with transformation capacity augmentation at Bhadla PS. Above proposed system was identified to cater to LTA applications received (2.85 GW) recently in above complexes and to cater to some future potential at the locations (Fatehgarh, Bhadla/Phalodi & Bikaner) as well. 2.4 RVPNL stated that the Rajasthan intra state network is already facing high voltage problem due to RE addition and addition of this inter-state transmission system in Rajasthan would add to the high voltage problem under no solar generation conditions. RVPN also stated that in view of NHAI crossing, line crossings and severe RoW problems, RVPNL is unable to frame suitable proposal for utilisation of 2 no. of 220 kV line bays at Sikar 400/220 kV sub-station allocated to them under the scheme “Augmentation of transformation capacity at Mainpuri and Sikar”. RVPNL requested to allocate the 220 kV bays for solar / wind developers or utilise for any other purpose. 2.5 CTU stated that studies were carried out under no solar condition in one of the scenario and suitable reactive compensation has also been planned in ISTS as part of proposed scheme. The RE potential is envisaged in Western Rajasthan, from where new ISTS transmission system needs to be planned for its evacuation.
